To all Lv/0m t may concern:

Be it known that I, VERNON RoYLn, a citizen of the United States, and resident of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Edging-Machines, of which the following is a specification.

My invention relates to what is known in the art as an edger, for use in finishing blocks and plates for the printing press, and is directed more particularly to the dimensioning gage. and parts which intimately coact therewith, particularly a micrometer, the object being to improve the accuracy and increase the output of the edger and at the same time leaving the edger free to be used independently of the improved gage.

A. further object is to provide a micrometer as a unit capable of being used in connection with gages of other machines than the edger.

In the accompanying drawings,

Figure 1 represents a plan view of a portion of' the edger showing the parts in the positions which they may assume in relation to a plate to be operated upon.

Fig. 2 is a side elevation of the work carrying table and parts carried thereby.

y Fig. 3 is an enlarged detail side view of one of the removable (pica) stops, showing a position of the same in broken lines thrown out of use.

Fig. 4 is a. horizontal section through the F 5 is a transverse section of the same taken in the plane of the line A-A of Fig. 4.

Fig. 6 is an enlarged transverse section taken in the plane of the line B-B of Fig. 1.

Fig. 7 is an enlarged detail elevation of the auxiliary micrometer or measuring device.

Fig. 8 is a central section taken in the plane of the line C--G of Fig. 7, and

Fig. 9 is an enlarged transverse section taken in the plane of the line D-D of Fig. 1.

The table on which the work is supported is denoted by 1. It is mounted on suitable ways to slide bodily with work thereon along` the face of a cutter 2, in the present instance a rotary cutter, the term cutter being used hereinafter to denote one or more cutting blades or edges as may be desired, 'the same forming, per se, no part of my present invention. The table 1 is made large enough to accommodate the ordinary of blocks and plates when the dime sioning is in position thereon and unusually large sizes may be trimmed by removing the said gage, the removal requiring but a moments time.

For holding the work at the front end, there is a clamp 3 provided and for holding the work at the opposite end, there is provided a sliding clamp 4 which presses the work to the table with a vise-like grip. The specific structures of these clamps are not made features of the present invention.

The body of the dimensioning gage is denotedrby 5. It is provided with an extended tongue 6 on its under side, which tongue fits accurately in an elongated slot 7 in thetable, the slot extending at right angles to the path in which the table moves, so that the gage body may be slid toward and away from the path of the cutter in a right line. The slot 7 and tongue 6 are preferably tapered in cross section, as shown.

A rack bar 8, provided with spiral teeth 9 on its lower face and with a fin or rib 10 on its upper face, is located in an enlarged slot or channel 11, directly beneath the slot 7.. The fin 10 extends upwardly into the bottom of the slot 7 and receives a stud 12 projecting downwardly from the tongue 6, to removably lock the body of the gage to the rack bar 8. rlhe bottom of this channel11 is cut away intermediate of its ends to expose the teeth on the rack bar 8, and these are engaged by one or more, in the present instance two, spiral toothed driving pinions or worms 13, 14, on a shaft 15, supported in a split sleeve or bearing 16 fixed to the table support. To that edge of the gage body 5 toward the cutter, a fence 17 is pivoted, as shown at 18, 19, Fig. 1, so that it may be thrown back out of the way of the workman when he is adjusting a block or plate for the first cut. The fence 17 has a dove-tail groove 20 extending longitudinally along its face for the reception of detachable extension pieces 21. 22, for the purpose of advancing the work edge of the gage to a point nearer the path of the cut ter than the outer edge of the plate clamps 3 and 4, or either of them, to dimension short and narrow work. These extension pieces and termed stops and are known in connection with the present subject matter as pica stops, being made eighteen picas in length foi` reasons which will hereinafter appear. They are each provided with a deve-.tail tenen@ 23. t9 .enable them t@ be attached to and slid along the groove 20, and the dovetail tongue is locked to the stop 'by means of a screwtlneaded shank 24 extending from the back of the tongue through a socket 25, a set nut 26 on the outer end of the shank serving to clamp the stop to the tongue and the tongue to the walls of its groove. A spring 27 located between the nut and the bottom of the socket serves to cushion the parts and take up lost motion as the stop is slid along the groove with the nut slightly loosened. The pieces or stops 21, 22, may be used singlT or together as may be desired.

The body 5 of the gage is provided with a dove-tail groove 28 for the reception of the dove-tail head 29, of a bolt 30 which projects upwardly through an elongated slot 31 in a sliding bar or plate 32. The plate 32 is provided with a shoulder 33 near one end, to engage astop to be hereinafter described, andthe bolt 3() is provided 'with a winged nut 34 to clamp the plate 32 to the body 5 of the gage in the desired position. The bar or plate is guided along the groove 28, by a shallow tongue 35 extending along "the bottom of the plate into the neck of the groove 28.

The table l is provided with a dovetail groove 36 ruiming parallel with the groove 28, inthe gage body 5, and in this groove there `is seated the dovetail head 37 of a bolt 38 which extends up through a sliding block 39', the screw-threaded upper end of the bolt 38 Vbeing provided with a tail nut 40 for clamping the block 39 to the table. The block 39 is guided along the groove 36, by a shallow rib 41 on its under side which projects into the neck of the groove 36. lThe said block 39 is further provided with an offset 42, which lies in the path of the shoulder 33 on the sliding plate 32.

To lock the gage thus far described to the table l, in the desired position, there is provided a dovetail groove 43 in the table 1, for the reception of the dovetail head 44 of a bolt 45 which extends upwardly through the body 5 of the gage and is provitledon its screw-threaded upper end with a wheel nut 46. To assist in guiding the body of the gage "along the table 1, the bottom of said body 5 is provided with a shallow rib 47 depending into the neck of the groove 443.

The dimensioning gage hereinabove particularly described and exclusive of the rack bar '10 and the pinions for driving it, may be used by executing its movements by the direct push 'and pull of the hand of the workman, as follows:

rPhe table having been drawn forward so as'to leave room for positioning the plate and the dimensioning gage having been slid away from the cutter and its fence turned upward and backward of the table,

the-plate is first trimmed or edged by arranging it according to certain marks thereon, Iso that the edge toward the cutter will becutin a right line along the indicated path. rlhe plate is thenclamped in position and that edge is trimmed. The plate is then released and its trimmed edge placed against the straight edge at the front of the table with its end in position to receive a cut at right angles to vthat just made and in accordance with-certain marks on the plate, if such there be and the cut is made. t is at this point that the dimensioning gage comes into use for giving the plate the desired length and width. To accomplish this, the gage fencel is turned down onto the table, and assuming that the length of the plate is suiliciently great to dispense with the use `of the extension pieces, the engaging edge of the fence is adjusted the exact length of the plate back from the path of the cutter and the block 89 'slid along the groove 36 until its 'offset 42 engages a shoulder 48, see F ig. 1, on the back of the head of the body 5 of the gage. rlhe block 39 is then clamped in position and the dimensioning gage is moved toward the path of the cutter until the engaging edge of its fence reaches a point distant from the path of the cutter the exact desired width of the plate. The sliding plate 32 is then released and slid. along on the body of the gage until its shoulder 33 engages the offset 42 on the block 39, and is then clamped to the body 5 of the gage in rlhe table is drawn back, the plate is turnedwith its' trimmed side against the edge of the gage, the gage is moved forward until the shoulder 33 engages the offset on the block, and after clamping the gage to the table, the table is moved forward and the final lside of the plate is trimmed, giving the plate the exact width desired. v 4

No further adjustment is required for trimming successive plates to the same dimensions, as the stops, to wit: the block 42 and plate 32, determine these dimensions for each succeeding plate.

Whenever a group of plates of a different size is to be trimmed, the stops may be reset and satisfy the conditions for that group.

Of course if but a single plate were to be trimmed of any given size, therewould be no necessity for utilizing the stop as the gage could be clamped inthe two positions for length and width consecutively and the plate trimmed after each adjustment.

In order to relieve the workman from ad justing the gage by act-ual measurement and to furnish at the same time, if desired, adjustments in strict accordance with printers points, l have provided gear for operating the dimensioning gage and for associating therewith a micrometer disk Which may be in accordance with linearl units of English measurement, if so desired, but which Will be explained in connection with sub-divisions with the printers point as the standard.

The shaft 15, carrying the driving pinions 13, 14, hereinabove referred to, has also thereon a spiral toothed pinion 49 in mesh with a spiral toothed driving Wheel or Worm 50 on a shaft 5l supported in suitable bearings beneath the table support 52 and extending forwardly to a point in convenient reach of the operator at the front edger. The shaft 51, toward its front end, has keyed thereon a bearing disk 53 which rests against the shoulder 54 on the shaft, and the rim of which engages an annular bearing face V55 on the inner side of a micrometer disk 56. The micrometer disk 56 is mounted to turn on the shaft 5l, when released from t-he disk 53, and its outer face 57 lis subdivided into units having for their standard the printers pointwhich is about one-seventy second of a linear inch. y

In proximity to the micrometer disk 56, there is a stationary disk 5S xed to the table support and carrying an indicating line 59 thereon as the point of origin for measurement. rllhe micrometer disk 56 is further provided With a knurled Wheel 60 for `conveniently rotating it When released, and exterior to this knurled Wheel 60, there is keyed on the shaft a hand Wheel 6,1, conveniently provided With a handle 62 for rotating the shaft 51. A nut 63 screwed on the end of the shaft 5l against the hub of the wheel 6l, serves to slide the hub of the wheel 6l against the hub of the micrometer disk and thereby force its annular bear ing face 55 against the rim of the bearing disk 53, to lock the micrometer disk so that it shall rotate With the shaft 5l when so desired.

ln practice, the face 57 of the micrometer disk is subdivided by fine lines into equal spaces of such Width that the rotation of the micrometer disk one space Will, through the intermediate gear, advance the gage the distance of one-half of a printers point, one hundred forty-four of these spaces being indicated. Each second line is made a little longer than the one preceding it to indicate an advance of the gage one prnters point, each sixth line little longer than the second and fourth line to indicate an advance of the gage three printers points, and each twelfth Furthermore,

each half pica receives a number summing up the spaces from Zero up, namely, 6, 12 and so on up to 72.

rlhrough the gearing hereinabove described, a complete rotation of the micrometer disk 56 will move the dimensioning gage forward six picas or seventy-two points. To :facilitate the reading and hence the setting of the gage, a secondary micrometer disk 64 is provided and loosely mounted on a shaft 65 set in suitable bearing 66 beneath the table, the said shaft 65 having a spiral toothed pinion 67 thereon in mesh `with a spiral toothed portion 68 on the shaft 5l. The disk 64 has an inner annular bearing face 69 which engages a disk 70, keyed to the shaft 65 and resting against a shoulder 7l on said shaft. A stationary disk 72 With its face in alinement With the face lof the disk 64, is iixed to the support 66,

and has marked thereon, by a line line, a point of origin 73, to coperate with the subdivision of the micrometer disk 64. The outer portion 74 of the disk 64, of the micrometer is knurled on its cylindrical surface for convenience in manipulating the disk, and the said disk is locked to rotate With the shaft by means of a nut 7 5 on the screwthreaded end of the shaft 65 Which presses against a Washer 76 keyed to the shaft and resting against the hub of the micrometer disk 64, so as to force the micrometer disk against the bearing disk 70.

The said micrometer disk is furthermore formed in t\vo sections, the one section 64 with the knurled portion 7 4, having a movement relative to an inner portion 77, as follows: The end of the disk 64, 74, is provided With an elongated curved slot 7 8 through which a clamp screw 79 extends, and is tapped into the inner section 77. This screw 79 serves to clamp the two parts of the micrometer disk together or release them one from the other as may be desired.

In practice, the curved face of the micrometer disk 64, is subdivided into equal parts, each corresponding to a revolution of the primary micrometer disk 56, viz: six picas. As the disk is manipulated, it has fteen of these six pica subdivisions. The length of t-he slot 7S is such that if the clamp screw 79 be released, the part 64, 74 of the micrometer disk may be rotated on the inner part 77 Without disturbing any of the other adjacent parts, a distance of three subdivisions or eighteen picas. The length of this slot coacts intimately with the extension pieces or stops 21, 22, hereinbefore described and is employed 'to set the micrometer to zero when the extension pieces or stops 2l, 22, are employed. For example, When the stops 2l. 22, are placed in position on the Working face of the gage. their length being eighteen picas,- the primary micrometer disk and shaft connected therewith, will be turned backward three revolutions to"account for the length of said stops 21, 22. rlhis will leave the primary micrometer diskat Zero, but it will leave the secondary micrometer disk (54; three subdivisions from zero, viz: eighteen picas. All it requires 'then to set the secondary micrometer disk in harmony with the primary micrometer disk is to release the clamp screw 79 and turn the micrometer disk (il: the length of the curved slot 78 to bring it to Zero ready for the work of din'iensioning.

Inoperation, a plate having been alinedv withoutany further setting.

Particular attention is called to the structures hereinabove described which admit of the micrometer disks, both primary and secondary, being free to be rotated on their shafts independently of the shaft. This feature becomes of practical importance as follows: Cutters will wear and in sharpening and resetting they may not project exactly to the positions which they originally occupied and hence an error in measurement would arise were there not means for accounting for this difference in position. To account for this difference, when a new cutteris placed in position, the gage is moved forward into contact with the cutter and the micrometer disks are then released from their shafts and accurately adjusted with their zeros on the point of origin mark when the disks are again clamped to the shafts and work again proceeds.

When the gage is used in connection with work which has no mark to indicate the line of cut along its edge other than the subject, for example a picture, it is important that the plate be squared with respect to its subject, and to this end there is provided a subject squaring gage S0 hinged to an arm 81 to swing vertically the arm 81 being hinged to a, slide 82 provided with a clamp nut 83. The slide 8:2 is arranged to move along a dovetail groove Sil in an upwardly projecting rim or fence 85 of the table, the said slide 82 being provided with a shallow downwardly projecting rib 86 which travels along the neck of the groove 84q the dovetail head 87 of a clamping bolt being arranged to travel along` said groove 84, and the threaded end of the bolt extending through the slide 82 to receive the 65 certainty as to the accurate measurement itself as it is constructed so that the measurements can be readily read and the parts are of such size and structure that they will prove durable and dependable while they have that refinement of action required of an. instrument of precision.

`While, as before said, the micrometer disks may be subdivided to indicate in accordance with other standards than the point system, the latter is desirable as the pica is invariably used as a unit of length in measuring the line of type and both dimensions of a printing plate.
